On dynamic models of flotation with sedimentation
Flotation is a separation process where particles or droplets are removed from a suspension with the aid of floating gas bubbles. One application is dissolved air flotation in industrial wastewater treatment. One-dimensional models of flotation have been confined to steady-state situations for half a century by means of the drift-flux theory. A new dynamic model with partial differential equations is used which also includes the simultaneous settling of particles that are not attached to bubbles. Optimal steady-state operating conditions can be chosen by means of operating charts. Responses to control actions are exemplified by simulations with a new numerical method.
